9.2 B-Factors and Flexibility

B-Factors and Flexibility (Module 9: The Optimizer). Key concept: B-factors indicate flexibility. Read B-factors to separate mobile regions from rigid ones.

• Read B-factors to separate mobile regions from rigid ones
• Identify a flexible loop that is a stability liability rather than a functional feature
• Recognise that a chain terminus is often but not always mobile — read the map instead of assuming
• Distinguish disorder that reports on function from disorder that reports on where the chain stops
